1. Estimate the half-life in days (with respect to chemical transformation) of methyl bromide (CH,Br) present at low concentration (i.e., < 1 mM) in a homogeneous aqueous solution (pH-7.0, T = 25 °C) containing 100 mM chloride, 2 mM nitrate, 1 mM bicarbonate, and 0.1 mM cyanide. The half-life of CH,Br in water at pH 7.0, T- 25 °C is 20 days. What is the most reactive nucleophile out of all those present irrespective of concentration (i.e. don't just tell...

The reaction of sucrose with water in an acidic solution is C12H22O11 + H2O ---> C6H12O6 + C6H12O6 The reaction is first order with a rate constant of 6.17 × 10-4 s-1 at 35 °C, when [H+] = 0.10 M. Suppose that in an experiment the initial sucrose concentration was 0.40 M A) What will the concentration be after exactly 4 hours (i.e., 4.00 h)? B) How many minutes will it take for the concentration of sucrose to drop to...
